Smart-Lock Hacks Point to Larger IoT Problems

In my completely non-rigourous study of adoption patterns (I asked my friends, mostly people in tech/security roles), I’ve concluded that I’m right to be extremely suspicious of ‘smart’ devices. Articles like this just reinforce my world view. For the sake of full disclosure I must state that I’m working with a company that provides smart access services (not just lock/unlock but room reservations, car park slots, wifi codes, coffee, payment systems…) that is much more cautious than slinging some ideas on Indiegogo…:
